To all whom it may concern.' l

Be it known thatI, CHARLES A. JUENGsT, a citizen of the United States,and a rsident of Croton'Falls, in the county of Westchester. and Stateof New York, have invented certain new and useful Improvements inPamphlet-Coverers, of which the following The present invention relatesgenerally to book covering machines, and has for its main object theprovision of means whereby the book to be' covered may have the back cntoii and roughened, an adhesive applied to the back,.,a reinforcing strip4attache to the ,-back, and acover applied, all. while the book istraveling continuously.

This invention is an improvement-upon Angustl, 1916, No. 1,193,395. Inthatcase the cover is preferably applied 'to a book whichhasbecnstitched. In the accompanying drawings the invention is disclosedin` a .concrete and preferred form, but changes of Vconstruction may bemade without departing from the'leg'itimate. and expressed'scope of theclaims.

50 indicates a 'book conveyer composed y. of the'book clamps 55 hingedtogether and 'provided with `rollers260 which travel/in A "the 'upperandv lower longitudinal guides 261 of the framework.

(Figs. 2, 5 to 8 .and 41.)vv At the ends of the guides 261 are -npperand vlower sprockets 262, after the 'manner disclosed in my said priorPatent No. 1,1% )3,395, which engage the said rollers 260 to propel theconveyer. (Figs. 3 and 4.) MountedA on. thelnks'or clamps 55 of theconveyer arefurther the bearers 263 which travel between the upper andlower i guides 261 and between" the upper and lo-wer sprockets 262, all'as disclosed prior application.

The book conveyer '50 is thus in ,the form of an endless conveyertraveling preferably with a continuous movement in a horizontal planevand arranged with two parallel sides in my said and curved ends as shownin Figs. 3 and 4.

The machine is preferably arranged to be. connected up to a signaturegathering machine, from which latter the books 52'are delivered, in anupright position with their lbacks lowcrmost, -by means of the guides264 and chain 265 passing around the sprocket 266 (Figs. 1v and Arrangedadjacent to one of the parallel sides' of the hook convcycr 50 are thevario i instrumentalities which het upon 'the 1 hooks.. Theseinsi-ru'mentalities or devices are best seen in their relation to eachother ,and to the book convertir 50 in Figs. l. 2, and 4. As thereshown, they are merely designated by a general rcil'ercnrc izharaclrr,the Edetailed construction being shown more clearlyin the various detailviews.

Accordingly arranged. adjacent to thc book conveyer 50 is the papercutting device adjacent parts partlyin seclwhich cuts olf the back ofthe book and lis designated by the reference character l51.

Next thereto follows the paper roughenmg device whosel casing isindicated by 7 7. Then comes the preh'eating device for heatfing theback of the book before the adhesive is applied thereto indicated by104, and next thereto is the adhesive applying means indicated by therollers 89. 113 is the cover presser or drum and, interposed betweenitand the adhesive applying means, is the feeding means indicated by thereel 115 and the feeding and cuttin device 267 for feeding theremforcing str1p to the back of the book. Located adjacent to. the otherend of the machine is the cover feeding device 268 from which covers arefed by means of the guides 179 and chains 177 to the cover',v

standing ofthe relative location of the va rions mechanisms with respectto the book conveyer 50, we no w proceed to a more detailed descriptionof the machine. A

Adjacent to the path of the book conveyer 50 is a paper cutting machinewhich is now obtained a general underdesignated by the general referencecharacter 51. (See also Figsw9, 11, 12, 13 and 14.) i i v The papercutting device is arranged to act 4on the book or stock 52fed by theconveyer, preferably without sto page of the book conveyer, and hasthere ore imparted to it .a cutting motion towardand in the samedirection as the book conveyer.

The paper cutting. machine preferably has a pressure exerting means 53anda cutting member 54. These-are so. arranged that'thc pressureexerting means 53 reach-es the book clamping means 55 of the book fconveyer 5U betere the cutting member.` 54 engages the book, the cuttingmember 54 .continuing its 'movement while thc pressure exerting means isengaging the clamp 55 and traveling along with it.

On the other side of the path of the book conveyer' is .an aiutmentmember 56 and a backing member 57. The backing member 57 coii]' erateswith the cutting member 54, and the abutment member 56 cooperates withthej pressureA vexciting means 53. The

members 56 and 57 travel longitudinally with the book during tliccutting operation, but have no transverse movement.

Variousmeans may be provided ,for imparting the inward and forwardmotion to `the cutting umchinc, but in the present in stance an'eccentric device preferably utiliz/,cd for this purpose because of itsfaim plicity. 1t is preferred, however, to have '66 The' rotation but asingle source of power for all of the members of the cutting machine.But inasmuch as an eccentric or crank lmotion i parts a variable speed,and inasmuch as t e pressure exerting means must travel for ward atsubstantially the same speed as the book conveyor, the speed of'which-is unil form, suitable compensating devices are 11tilized to ermitthe pressure exerting means .O speed while engaging the clamping meansof the bock conveyor.

The preferred embodiment of the paper cutting machine is therefore asfollows:

15 A supporting member is'provided composed of two parts 58 and 59 whichreceives.

means of thel in the pressure exerting member and pins 67 pass looselythrough the member 58 and ,a're in threaded engagement with the member59. Surrounding these pins are the so springs 68 bearing against themember 59 and whose tension may becarl'ied by means of'the nuts 69.VVherel:3 the .p1ns7 pass through the diagonal lots 66 they are providedWithanti-riction rollers 70 ofa dian'i- 3'5 eter-substantially equal tothe width of the diagonal slots 66. 'The bolts 72 which fasten thecutting member 5f to thepart 58 of the supporting member. All thesedevices are arrangedofone side of the path of the book conveyezf.. Onthe other side of the path of the book conveyer there vis arranged aguide 72a rig;

The pressure exerting member willalso 'brecede, with the cutting 75 member until the" member 53'strikesagainst the stop 53, whenowing to the sl'ot conA struction, the said'.-member 53 will be brought forward of the cutting member.

Meanwhile the 'abutment member-andthe I80 backing member will havetraveled forward.

with the 'book at substantially the 4speed thereof, owing to theconnection between the' pressure exerting member and the carriage 3,and, after t to their original position.

Suitable means for roughenin the backs of the books or stock are provied. Prefl erably a horizontally rotatable roughening member is provldedwhich is disposed unf derneath and adjacent to the path of the books.- y

In its preferred form thisdevice, as shown infFigs. 9,- 10 and'll; isconstructed as follows: 4,7, 95 77 is a casing having the open top 7Sand the exit flue 79. Concentric with this casing is a verticalbearing, 80which extends partly inside the ca ing and partly below thesame'. 81 is a shaf 'dispop' d within this bearing 100 and receivingmotion-from the shaft E50-by means of the spiral gears 82. Mounted ad-Ajacent to the open top of the .casing on the shaft 81 is a s ider 83Vhaving-an annular vided'with hacksaw teeth held in position againstthc'pouter straight wall in the groove 84 by means of the annularfllingmember 11G 86 whose inner surface is. tapered to cornespend withthetaper of theinn er wall of the groove 84 as shown, and secured to thespider 83 by means ofscrews 87. Thejspider 83 thus forms a holdinmemberand in con- 115 illi g member 86 lholds same time this constructionpermits a quick removal4 and replacement of the band 85.

VThe book 52 passes substantially diametri- 120 cally across the face ofthe roughening member 85,4 and. the back ofthe book is thereforeprogressively ,rou'ghened throughout its entire length at an angle tothe direction of travel ofthe book, and in both directions l-beca'nsethe book enconnt'ers the saw twice at diametrically opposite points ofrotation in its passage over the same. This has the eii'ect ofthoroughly roughening the back .of

e book is out, will return B5 The particles of stock removed from thebook will work their way into the casin 77 through the open top thereof.If desire an exhaust (not-shown) vmay be connected to the exit line 79.In order to prevent the saw from displacing the sheetsof the book', Imay utilize the disks 88. These disks 88 are of relatively thin materialand are mounted to rotate or spin on the centers 88a at the top of thecasing 77, and are so arranged that they snipert or confine the outersheets of the bool; while the saW is roughening the back'of the book.

Proper adhesive applying means (Figs. 15 and 16) are utilized inconnection with the machine, which means may take many forms. I havefound, if an adhesive is appliedto the entire length of the back oftheook, that therewill .be an accumulation of adhesive at the tail end ofthe book-a condition Which is disadvantageous since the surplus tends tosmear parts .of the book not intended to be glued. I therefore prefer toconstruct the adhesive applying member in such a Way that the glue isapplied to the back. of the book for a distance less than the entirelength of the book, thereby avoiding the overplus of adhesive.

Also I provide a depressed portion inthe surface of the adhesiveapplying member into which the accumulation 'of adhesive co1- lects, anda scraper provided which follows the contour of the adhesive applyingmember and removes all suriiflns from the same. Tofacilitate theapplication ofthe adhesive, and to aid in keeping it in a fluidcondition While applying it to the book, I

lind it 'advantageous to heat the book before the glue is applied.

In the preferred embodiment herein disclosed these parts are constructed'as follows,

' (Figs. 1, 3, 15 and 16:)

89 is an endless adhesive applying member here shown as a roller,suitably journaled as at 90 for rotation within the adhesive container91. The member 89 is provided With an adhesive applying surface 92 and adepressed surface or rap 98. The surface 92 is of a length less tian thelength of the back ofJthe book, or the surfaces 92 and- 98 arcso relatedcireumferentially with relation to the travel-of the book that the sur-92 will not contact the tail end 94 ofthel book (Fig. 15). The surplusadhesive will therefore collect .on'tlie surface 98 of the roller 89.The roller 89 is preferably provided with two surfaces 92 and two gaps93.

95' is a scraper the rock-shaft-QG. Mounted fast on the rockshaft 9G isan arm 97 aiulcarried 'by the scraper 95 is also an arm' 98. between thetwo arme is a spring 99 the tension'of which may be adjusted byv meansof the Wing nut 100. This serves to hold blade mounted loosely enInterposed the scraper against the roller 89 under a yielding tension. i

By varying the position of the scraper, bringing 1t nearer or fartheraway from the roller 89, the thickness of the glue film may be varied.

.Connected to the roekshaft 96 is a cam follower 101 engaging the cam102 and held thereagainst by 'the spring 103'. As will be -seen from aninspection of Fig. 15 the earn 102 is of vthe-same contour as the roller89,

'so that the scraper 95 Will hug the surface of the roller 89 .at alltimes.. The adhesive applying surfaces 92 are roughened as shown in Fig.16, While the gaps or depressed surfaces 98 are smooth. The direction ofrotation of the roller 89 is shown in Fig. l5. It Will now be apparentthat the i rotation of the roller 89 will cause its sur- Imay besqueezed down by the book and sur- `face' 92.

Arranged adjacent to the path of the book conveyer and in advance of theadhesive applying means is a preheating meinber, here taking theform ofa steam chest 101 over which the back of the book passes so as to heatthe paper before glue is ap plied. Steam is supplied to this chestthronghthe pipe 105 controlled by valve 106. A branch pipe 107 leadsfrom the pipe 105 to the steam chamber 108 of 'the adhesive containerfor keeping the adhesive in a fluid condition. A valve 109 controls thebranch pipe 107. In the present instance two rollers 89 are employed andthe book may therefore be given two applications of adhesive..

If a' surplus of glue has been applied to the book it sometimes happensthat it will. form into downwardly projecting whiskers or points. Inorder to remove this surplus there is provided a spinner 110 in rear ofthe 'adhesive applying meniber, below the path of the book but closelyadjacent thereto. As here shown this spinner or .surplus removing memberin the form of book and the cover.

' In'the machine under consideration such means may be provided, toproperly coperate with the traveling book eonveyer and the endless coverpresser or cover drum 113.

Itis convenient to feed the reinforcing means in the form of a web ofmaterial and to provide a cutting device for severing the web.. Meansare also provided for interrupting the feed of the web when the cut- 0,ting device acts to sever said web. The parts are further so arrangedthat the reinforcing strip and the -cover are applied slmultaneously Atothe book. This is accomplished by. feeding the reinforcing material andthe cover in between the book and the cover presser, or, to state itdiiferently, by feeding the 'reinforcing strip 1n between 'the cover andthe book; In this manner the book may be' continuously moved, if `de`V2-0v s'ired, while applying the reinforcing material andL the cover.

' In vthe` preferred form herein disclosed in Figs. 1 and 17 to 20inclusive these parts' are arranged as follows:

' 113 is an endless cover presser, here shown lin the form of a drum towhich a cover 114 is fed by any su'table xneans-preferably by the means.heren after described. 115 1n- {fdicates a rotatable reel for holding a`web 116 of reinforcing material, like crash or 4cheese cloth. Above thesame are twn feed rolls 117. and 118 adjacent to the. p'ith 'of the hookconveyor. Between these two rolls the web 116 is led by meansl of theidler 119 and guids 120. The roll 117 is mounted to rotate freely uponthe stud '120El fixed in the frame of the'machinewhile the-roll 118 ismounted on the rocker arm 121 extending rigidly from the sleeve 122rotatable on the iixed stud 123. Conner-.ted to the :trio 121 is' a. rod124 'which extends downwardly and is actuatedfrom the-cam 125 bymeans ofthe beam 126. having the cam roller 127. |Garried by each oi the rolls117 and 118 is a sprocket wheel 128. 4A sprocket chain 129 istrained'from the sprocket 130 aroul'u'l the idler 131 and then inopposite directions around the wl'icels128 and thence'baek to the wheel130. In, this `way the 4proper rotabe tion is given to, the rolls 11.7and 118, the separation of the said rolisffrmn one anotherV whileVremaining in rotative engagement with the; drive 4chain 130 being alsopermitted by this construction. Y

Mountednnderneath,the pathof the web 116 and transversely thereof astationary l cutting member 13.1. Located above the. path of the web 116and extending transversely thereof is: movable cutting member '60 '132.This member 182 is rnminted .on the rockingsupport aridis normally heldoutof engage-.ment with the-web by `:means of the'spring .1B-4.''Connect-alto the rock. ing sleeve '122 is an extensionlje having ordrum'by any suitable'means.

It will now be apparent that the rotation l'actuate the 'sleeve 122whereby the cutting member 132 will sever the web, and at the same timethe rolls 117 and 118 will become separated, thereby interrupting thefeed of the web.

The cover may be fed to the cover presser I have however,l :devised anew and improved sheet separating and feeding means which may beadvantageously used in connection with and as a part of the bookcovering machine.

A combing Vwheel is employed which is adapted to support a pile ofsheets, and means are provided for lifting the pile off the combingwheel in rear' of the lowermost l' sheet so that the said lowermostsheet may be readily vwithdrawn while the pile is lifted. Preferably theadvance -ofthelowermost sheet is 'utilized to control the actuation ofthe pile lifting means. The pile-lifting means really `constitute asheet feed interrupting meanmand it is preferred to aotuate this devicehydraulically, and to have the Y sheet actuatea valve controlling thehydrau` lie device.' Means are also provided for supporting. the rearend of the 1pile independently of the Ac.o1nl')in., u; wheel, and forthis purpose I utilizes-hopper and suitable .means for adjusting thesame.

The preferred"embodiment oi this device is shown in Figs. 2, 34,154, 35,Btg 557, ,38, 3S) and 40. r
